Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed December 9, 1912. Serial No. 735,718.

To all whom it may concern Be it known that I, WVILLIAM F. STRAUB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Time-Recorders, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Hy invention relates to time recorders and has for its object the provision of an improved device of this kind in which very efficient mechanism is provided for operating stamping mechanism, and in which improved means are provided in combination with a stamping mechanism for setting purposes.

Generally speaking my invention contemplates new and improved electromagnetic mechanism remotely controlled for setting the time stamp. This electromagnetic mechanism which sets the stamping mechanism at the same time serves to drive suitable hands for indicating the time which are as socia'ted with the device. This setting mech anism likewise serves the purpose of operating suitable adjusting mechanism for ad justably supporting a card upon which the impressions may be made.

I will explain my invention more in detail by reference to the accompanying drawings, illustrating the preferred embodiment thereof in which- Figure 1 is a partial longitudinal sectional view of my improved time stamp; Fig. 2 is a top detail view of the ele0tr0magnetic controlling mechanism; Fig. 3 is a top view of the operating mechanism through the agency of which the impression is made; Fig. 4 is a detail view illustrating certain features of the device; and Fig. 5 is a perspective view of certain parts of the operating mechanism. Fig. 6 is a view of the card. Fig. 7 is a view of the gong.

My improved device is provided with the ordinary stamping gear wheel train 1 which is adapted to stamp impressions upon cards placed within the card chute 2. The depth to which this card enters the chute depends upon the position of certain projecting fingers 3, which fingers are suitably carried by a chain 4, which chain is carried by and driven by means of the sheave 5. There are a pair ofupper sheaves and lower sheaves wheel 11.

as will be apparent from Fig. 3, the upper sheaves being mounted upon a shaft 6, and this shaft carries a worm wheel 7 adapted to be driven by a worm 8 carried by a shaft 9,

.position of gears 14 and 15 to operate the hands 16 and 17 of a clock which is suitably 1 placed at the top of the casing 18. This casing 18 together with the hood 19 incloses all of the apparatus of the time stamp, the whole structure being adapted of course as is customary for mounting on the wall or In any other desired manner. The gear 11 also meshes with a pinion 20, which pinion through the interposition of the shaft 21 drives a bevel gear 22, which bevel gear meshes with a companion bevel gear 23 to thereby drive the stamping gear train 1. The gear wheel 11 which thus by meshing with the pinions 10 and 20 drives all the various parts which require to be set is driven through the agency of a suitable armature 24 to which said gear is fastened. This armature 24 is mounted on a suitable .shaft 25, thus being rotatably mounted and has its position controlled by three electromagnets 26, 27 and 28. The general outline of this armature will be readily apparent by referring more particularly to Fig. 2, and it will then be seen that this armature has a plurality of inwardly projecting pole pieces 29, 29. In order to have the electromagnets control the periodic rotation of the armature the magnets 26, 27 and 28 are energized in rotation, that is, first the electromagnet 26 is energized, then the electromagnet 27, and then the electromagnet 28, following which the same cycle recurs and the series of energizations is carried on in this'manner.

It will be seen that while a pole piece 29 of the'armature 24 is over the electromagnet. 26, that a pole piece 29 of this armature is in close proximity to the electromagnet 27 and the energization of the electromagnet 27 will thus rotate the armature, say clockwise. Then if electromagnet 28 is energized and electromagnet 27 then deenergized, the armature will further be rotated clockwise as the electromagnet 28 attracts its adjacent P916 piece 29.- In this way suitable electromagnetic driving mechanism remotely controlled sets the various parts of the time stamping mechanism. Of course any suitable wiring system and any suitable master control system may be employed to periodically and in regular rotation energize the electromagnets 26, 27 and 28.

It will be seen that the stamping gear train is mounted forwardly of the chute within which the card is to be placed and this gear train is of course moved back wardly away from the path of the card so that the card can be readily inserted. WVhenever an impression is made on the card it is necessary to suitably actuate the handle 30 and by means of mechanism to be presently described the time during which the stamping wheels and the card remain together is very short irrespective of whether the handle 30 is or is not held in its actuated position. It will thus be seen that the holding of the arm 30 will not prevent a setting of the stamping wheels by means of the electromagnetic mechanism heretofore described.

By referring to Fig. 3, I show a toothed wheel 31 which whenever an impression is made has its teeth engaged by a pawl 32 which alines the shaft carrying the gear train should there be a slight displacement from the particular position which the stamping wheel should occupy to give the best impression upon the card. The handle 30 is securedto a lever 33 which is pivoted upon the shaft 34 fixedly secured in the end pieces 35, 35. Whenever this lever 33 is actuated it oscillates an arm 36, which arm thereupon oscillates a shaft 37. This'shaft 37 carries a crank 38 adapted to oscillate a pawl 39. This pawl 39 periodically moves the stepliy-step wheel 40 one notch. This step-bystep wheel 40 is secured to a roller 41 about which an inking ribbon 42 is carried. This inking ribbon also passes around the rollers 43, 44 and the tension adjusting roller 45. This ribbon passes in front of the stamping wheels and between said stamping wheels and the card. Every movement of the pawl 39 shifts the ribbon a. short distance so that the ribbon is continually being shifted. The roller 45 is carried upon an arm 46 held in place by a spring 47, thus to maintain the ribbon 42 in a taut position. A holding pawl 48 prevents the return of the step-by-step wheel 40 and a spring 49 presses the pawl 39 against said step-by-step wheel 40.

The lever 33 as before stated is designed to cause the making of the impression upon a card whenever this lever is actuated. The shaft 50 which carries the gear train is mounted between two links 51, 51, which links are preferably secured to a shaft 52- upon which two additional links 53 are also preferably associated at one of their extremities. The links 53 at their opposite extremities are pivotally mounted upon a shaft 54 rigidly held in the framework of the machine. The links 53 have downwardly extending arms 54 which are connected by shafts 55. A spring 56 by pressing against the shafts holds the parts, that is, the links 51 and 53 in their topmost position which is the one they occupy in Figs. 1 and 4.

A strong spring 57 unites the shaft 52 with a lever 58, which lever 58 is pivoted on a shaft 59, which shaft is rigidly held in the framework of the machine. The shaft 59 further carries a pair of arms 60, which at their upper extremities also are pivotally mounted upon the shaft 50. The lever 33 has a cut out portion 61, a portion of whose surface at 62 is formed of an are described about the axis of the shaft 34. Against this surface 62 abuts a bridge 63 which unites the arms 60. The link 58 carries a projection 64 which bears upwardly against a pawl 65, which pawl is pivoted to the lever 33 at 66 and is held in the position shown in Fig. 1 by means of the spring 67 holding this pawl against the limit stop 68. Now when the lever 33 is depressed the pawl 65 by bearing against the projection 64 carries the link 58 downwardly, thereby causing tension in the spring 57. It may be stated that if the parts are in the position shown in Fig. 1, that the spring 57 is in a state of repose and not under stress. The spring 57 being then under stress after the beginning of the movement of the lever 33 tends to pull the shaft 52 downwardly, but this it is unable to do because the links which are pivoted on the shaft 59 have their bridge 63 abutting against the surface 62 and are thus not in a position to move toward the right until at such a time when the lever 33 has been moved low enough so that bridge 63 clears the top thereof, at which time the spring 57 rapidly pulls the shaft 52 downwardly, thereby moving the shaft 50 and the stamp wheels to the right (Fig. 1) to make an impression upon the paper. Immediately this impression has been made the pawl has cleared the projection 64, thereby permitting the spring 56 by pressing against the arm 69 to again elevate the links 51, 53 and 58 to the position they occupy in Fig. 1. The arm 33 may then be permitted to resume its normal position, the pawl 65 clearing the projection 64 and again assuming its position on top thereof as shown in Fig. 1. A suitable spring, not shown, tends to raise the lever 33 to its normal position. I have thus set forth a very simple and efiicient toggle mechanism for effecting a momentary impression uncontrolled by the length of time required in the depression of the lever 33. Whenever the lever 58 moves downwardly, it permits a hammer 71 to fall away from a gong 72 and the recoil of the lever 58 causes this hammer 71 to strike the gong 72 whenever an impression has been made on a card.

Having thus described one form of carrying out my invention, what I claim as new and desire to secure by Letters Patent is:
